Science
Mechanism of Action
Lactobacillus acidophilus fermentation concentrates organic acids, primarily lactic and malic acids, to provide gentle enzymatic/chemical exfoliation by weakening corneocyte adhesion. Concurrently, grape-derived polyphenols like resveratrol and quercetin deliver potent antioxidant activity, neutralizing free radicals and protecting the skin barrier from oxidative stress.
